CIGARETTE-MAKING MACHINE.

Specification of Letters Patent.

Patented Sept. 26, 1905.

Application filed January 18, 1905. Serial No. 241,557.

To all whom it may concern:

Be it known that we, ANATOLE BENOi'r, JULIEN GUENIFFET, JULEs N ICAULT, and ETIENNE DANGER, mechanical engineers, citizens of the Republic of France, residing at 7 Rue DeparcieuX, Paris, in the Republic of France, have invented certain new and useful Improvements in Cigarette-Making Machines, of which the following is a specification.

The objectof the present invention is a cigarette-machi1ie of large production in which a core or cord of tobacco is formed and fed along continuously, while the paper tubes are carried by a drum moved intermittently along and round its axis. Each tube successively is moved backward and comes in a direction contrary to that of the core of tobacco over the end of the latter. Then immediately it is filled with tobacco it is moved forward. During this latter movement the core of tobacco is out without being stopped by a blade moved at the same speed of translation as the core itself. As soon as the cut is completed the drum is turned so as to present a fresh paper tube in front of the cut end of the core of tobacco, which paper tube is immediately moved backward to be filled by this core. The large production of the machine results from this mode of general working and from the employment of a special arrangement by which the drum receives averyrapidintermittentrotatorymotion. In fact, the filling of the paper tube is accelerated by the fact that the tube and the core of tobacco move in opposite directions. On the other hand, the cutting across of the tobacco is efiected without interrupting the forward movement of the latter. Finally, by reason of the arrangement which assures the rapid intermittent rotation of the drum the speed of the continuous movement of the tobacco may be relatively very great without the machine ceasing to work regularly.

The annexed drawings show by way of example a form of eXecutionof the object of the invention.

Figures 1 and 1 are vertical sections of the entire machine. Figs. 2 and 3 show a plan and elevation of the wheels for feeding forward the tobacco. Fig. 4 is a side elevation of a drum. Fig. 5 shows in vertical section, to a larger scale, some details of feedingtubes, of a knife, andof the drum. Fig. 6 is an elevation of mechanism for driving the drum. Fig. 7 is a section taken on line A A of Fig. 6. Fig. 8 is a plan of the same mechanism. Fig. 9 is an elevation of a part of the same mechanism. Fig. 10 is a front elevation of the drum. Fig. 11 is a plan of a pincer.

For the sake of clearness in the descrip-- tion we will designate the back of the machine that part placed to the left of Fig. 1 and the front that part placed to the right, the various movements of the mechanisms being related to the direction of movement of the tobacco indicated by an arrow in Fig. 1.

The general action of the machine is as follows: A transporting-apron a on which the tobacco is placed carries the latter between wheels b, which compress it and feed it forward in the shape of a continuous core or cord through a funnel c. In front of this latter is placed a drum d, rotated intermittently by the action of special mechanism e, placed at thefront of the machine. The compartments in this drum are filled with paper tubes f when they pass in front of the mechanism 9 for forming the tubes. Each tube is thus carried in front of the funnel c in order to be filled with tobacco. At this point there is also a knife h, which cuts the core of tobacco a little behind the paper tube. The cigarette is then carried by the drum successively opposite to a rammingrod 7;, Fig. 4, which rams the tobacco into the paper tube exactly flush with rear edge of the latter and opposite to anejector-rod which pushes the finished cigarette toward the front. The cigarette falls freely out of the drum at is, Fig. 6.

1 .The essential parts of the machine will now be described more in detail.

The endless apron is guided over cylindrical rollers 1 and has a continuous motion of translation imparted to it by means of driving-gear. (Not shown in the drawings.) Above the flat and horizontal part of the'apron are arranged the wheels 5, Figs. 2 and 3, comprising a vertical cylindrical wheel 3, two lateral horizontal wheels 4, the surface of which has an upper cylindrical part and a lower part of concave shape, a vertical grooved wheel 5, and two lateral horizontal grooved wheels 6. These wheels are rotated continuously by gear-wheels 7, so that they all tend to feed forward the tobacco passing between them and the apron. between the wheels 4 and 6 are placed guides 8, which embrace the wheel 5 and the wings of which extend into contact with the wheels 4 and 6, Fig. 2. These guides are supposed to be removed in Figs. 1 and 3. The surface of the wheels 3 to 6 is furnished with oblique flutes or striae which serve to feed the tobacco forcibly forward. The object of the inclination of the flutes or strize is to prevent fibers of tobacco being pulled out from the core of tobacco at the place where the wheels 4 and 6 are scraped by the rear points of the guides 8 and the funnel c in this sense that these points may lit the wheels exactly Without danger of shocks or of Wedgings. The successive action of the various wheels 3 to 6 in combination with that of the apron has for effect the regular formation of the core of tobacco and the feeding of it forcibly forward without compressing it more at some parts of its length than at others.

The funnel c, Fig. 5, is a tube fixed to an immovable support 9. On the front end of this tube is mounted so that it can slide another tube 10, fixed to aplate 11, having a toand-fro motion imparted to it. This telescopic prolongation of the funnel cis intended to support the core of tobacco always in immediate proximity to the drum d, notwithstanding the to-and-fro movement of the latter. The plate 11 and the drum d slide together on a shaft 12, the plate being mounted loosely on the boss 13 of the drum between the body of the drum and a loose collar 14, which is held by a ring 15, fixed to this boss. Nevertheless the plate 11 does not follow the rotatory movement of the drum. It is pre vented from turning by the spindle 16, fixed to it, and guided in fixed sheaths 17, forming part of the frame, while the drum (1 is driven with the shaft 12 by means of spindles 18, on which it can slide, these spindles being secured to a support 19, rigidly fixed on the shaft.

A to-and-fro movement is imparted to the plate 11 and to the drum (Z by an oscillating lever 20, connected to the collar 14 and operated by a cam 21. This latter is so constructed that in the first part of the forward movement of the drum (period of cutting) the speed of translation of the latter is equal. to that of the core of tobacco and that it is a little superior to the same during the last part of the forward movement of the drum, (period of rotation.)

The drum d is furnished with a disk 22, carrying a circular row of tubes 23, out like a whistle, intended to be placed successively in front of the telescopic funnel c. The drum also carries a crown 24, in which are formed grooves opposite the tubes 23. Finally,

In the space the drum is surrounded for about three-quarters of its circumference by a guideway or guard 26, which is fixed by cross-pieces 27 to the plate 11, so that it follows the drum in its to-and-fro movements, but without turning with it. This guideway 26 serves to keep the paper tubes in the grooves of the drum. It serves also to support the shaft 28 of the knife h and to move it in its to-and-fro movement by means of wings 29. The mechanism c, producing the rotatory movement of the drum, is shown in detail in Figs. 6 to 9. On the shaft 12 of the drum are fixed a drivingwheel 30 and a stop-wheel 31, which when required may be made as a single wheel, and are furnished with prismatic notches on their periphery. A lever 32 is mounted loose on the same shaft and is connected by one of its ends to a sliding rod 33, guided on a continuously-rotating drivingshaft 34. This rod carries a roller 35, which takes into an eccen tric groove 36 of a plate 37, fixed to the shaft 34, so that the rotation of the latter imparts a to-and-fro movement to the rod and lever 32. The other end of the lever 32 is furnished with a radially-directed slide-guide 38 and in which moves a slide 39, carrying a tooth 40, intended to engage between the teeth of the wheel 30. This slide receives a to-and-fro motion by means of a grooved cam 41, acting upon a roller 42, placed on the slide. The said cam turns freely on the shaft 12 and has imparted to it a continuous rotatory motion by gear-wheels 43, which are propelled by a motor-driven shaft 34, so that at each rotation of the drivingshaft 34 the cam 41 causes the tooth to engage with the wheel 30 during a fraction of the revolution and causes it to disengage therefrom during the rest of the revolution. The arrangement comprises also a stop-lever 44, oscillating on a fixed axis 45 and operated at one end by a cam 46, fixed to the shaft 34, and at the opposite end by a spring 47. On one end of this lever is fixed a tooth 48, opposite to the Wheel 31, so that at each revolution of the shaft 34 the tooth 48 is engaged with the wheel during a frac tion of the revolution and disengaged therefrom during the rest of the revolution. The movements of the slide 39 and of the levers 32 and 33 are so coordinated that the tooth 48 is disengaged from. the wheel 31 after the tooth 40 is engaged with the wheel 30 and before the lever 32 oscillates in the forward direction indicated by an arrow in Fig. 6, and that afterward the tooth 48 engages with the wheel 31 after the lever 32 has stopped and before the tooth 40 is disengaged from the wheel 30. The return move ment of the lever 32 commences after the tooth 40 is disengaged and ends before this tooth engages afresh with the'wheel 30. The result is that the system of wheels 30 31 is is never left to itself and that its connections turned through an angle corresponding to the distance apart of twoiconsecutive-grooves The knife it has a continuous rotatory movement imparted to it and is arranged to pass into the narrow space between the plate 11 and the disk 22, ofwhich it follows at the same time the to-and-fro longitudinal movement. The knife is'fixed on the shaft 28, which is driven by power, so as to cut the core of tobacco during the forward movement of the drum, and consequently accompanies the tobacco in its continuous movement of translation.

On the guideway 26 are-also arranged two pincers 49 and 50, each of which consists of an india-rubber roller mounted-so as to turn on a spring 51, fixed to the guideway, Figs. 10 and 11. tically upon two of the tubes 23, which pass successively beneath them, and their object is to hold-the paper tubesf on the tubes 23 from the filling operation-to that of ejection.

The ramming and ejecting spindles t and j, Figs. 4 and 10, are fixed to a sliding piece 52,

which'has a .to-and-fro movement imparted to it by means of the rod-shown immediately to its left in Fig.4. They are of such lengths that the front end of the spindle 6 passes into the tubes 23 of the drum until flush with the spindle advances beyond the point of the said tubes. The spindle t serves to push into each cigarette the little plug of tobacco resting in the thickness of the disk 22 after the cut. The spindle'j serves to disengage end of the guideway 26.

The mechanism for making the paper tubes is well known. It is sufficient to say here that the continuous tube formed on the spindle 5-3"by' pasting or by hooking one edge of the strip of paper into the other edge is cut by the scissors 54, having a-to-and-fro movement imparted to them in such manner that at the moment when the drum d-does not turn and is moved forward the scissors 54' ]i)L1Sh6d by the scissors 54 onto t e tube 23 l is rought to the interior of the guideway 26 Each of these rollers rests elas- I Ztial rotation of the drum takes place.
